Which of the following equations is of a parabola with a vertex at (3, 0) ?

Oy=x^2+3

o y=x^2-3

Oy = (x+3) ^ 2

y = (x-3) ^ 2

D. y = (x - 3) ²

Step-by-step explanation:

The parabola formula in vertex form is:

y = a (x - h) ² + k

where the vertex is located at (h, k). Replacing with vertex (3, 0) we get:

y = a (x - 3) ² + 0

y = a (x - 3) ²

In all possible options the leading coefficient a is equal to one. Therefore:

y = (x - 3) ²
